Seagate BlackArmor 420 is a decent NAS server. However, not having the capability to dynamically change the current RAID setup's capacity makes it much less desirable for either home or business users.

Based entirely on the Pogoplug service, the Buffalo CloudStor Pro NAS server makes a great investment for Pogoplug fans. Its lack of support for general local network features will make others think twice about getting it.

Designed to quickly turn external hard drives into a home storage network, the MediaShare Mini could use lots of improvement in regard to ease of use. Savvy users, however, will find it a fun device to have.
